OVal is an extensible object validation framework for Java 5 or later. Annotations (@NotNull) or XML configuration files can be used to express class constraints. OVal can optionally use AspectJ to enforce automatic validation (DbC)

public class ClassInfo {@NotEmptyprivate String school;
}

运行测试类

其他使用

@Size(min = 1, message = "查询类型不能为空")
private List<String> list;

@ValidateWithMethod(methodName = "isValidDate", parameterType = String.class
private String date;public boolean isValidDate(String date) {try {DateUtils.parseDate(date, "yyyy-MM-dd");} catch (ParseException e) {return false;}return true;}
